摘要
通过野外土壤入渗试验，分析了３种入渗公式中参数在该流域不同地貌特征与不同土地利用条件下的变化规律，探讨了不同地貌耕作措施、初始土土壤含水率、积水深度等因素对土壤入渗的影响．
It has been analysed that the laws of the experimental parameters in three infiltration equations use state and topographic conditions.Variational law of the infiltration rate has been approached from the topographical conditions,cultivated pratices,initial soil water content and accumulated depth,etc.
